Webinar: Gardening Under Native Trees

April 12, 2023 @ 7:00 pm - 8:00 pm

Mature native trees are a highly valued asset in both built and natural area landscapes.  Adding new plants and maintaining existing plants within the shade and root zone of large trees can present challenges for the trees and companion plantings alike. Misunderstandings about mature trees and their roots often leads to stress or death of trees intended for preservation.  This talk will cover practical and sustainable methods for improving the long-term success for the trees and surrounding landscape.

Register in advance for this webinar. After registering, you will receive a confirmation email containing information about joining the webinar.
